fasorr

Fasorr refers to a rare, short-lived heat haze that can develop on a bi-weekly basis under specific meteorological conditions in arid desert regions. The phenomenon is characterized by a brief, intense temperature inversion that adds a smoky or hazy appearance to the surrounding environment.

This atmospheric phenomenon is primarily linked to the interaction of high-pressure systems with dry desert air. Fasorr events often occur at dawn, a time of day when temperature gradients are typically at their highest. The rapid expansion and contraction of the air masses can cause micro-convection currents, which, in turn, produce the illusion of a heat haze.

Fasorr is generally limited to regions with extremely high temperatures and is most commonly observed in areas with sandy, fine-textured soils. Visual observations of the phenomenon have been documented in the Sahara Desert and the Gobi Desert, with researchers suggesting that specific desert dwellers have developed coping mechanisms for spotting Fasorr, which could be associated with adaptations related to food procurement or social events.

Despite the fast development of this phenomenon, research on Fasorr remains incomplete. Current theories suggest that unique cloud formations and air pressure patterns accompanying high temperatures lead to heat traps that strip the air of its humidity. Total durations of Fasorr events usually do not exceed a few hours. Given the limited frequency and restricted visibility, Fasorr often goes unnoticed, verified only through documentation by affected communities. More comprehensive studies are necessary to gain a deeper understanding of this unique phenomenon.
